Chapter 1: Getting to know your BLW-04G
This chapter describes the package contents and provides a list of features
and application illustrations of the BLW-04G.
1-1 About The BLW-04G
The BLW-04G is a hybrid design product which combines Ethernet technology
and wireless access into a single stand-alone unit. The device allows you take
advantages of both mobility and fast connection. All PCs whenever on wireless
LAN or Ethernet LAN can share files, printers and other network resource.
Moreover, all users can share single account of Internet access by having this
device connect to a DSL/Cable modem.
Ethernet / Fast Ethernet
Ethernet is the most widely-used network access method, especially in a Local
Area Nnetwork (LAN) and is defined by the IEEE as the 802.3 standard.
Normally, Ethernet is a shared media LAN. All stations on the segment share
the total bandwidth, which could be 10Mbps (Ethernet), 100Mbps (Fast
Ethernet), or 1000Mbps (Gigabit Ethernet). With a switched Ethernet, each
sender and receiver has the full bandwidth.
Fast Ethernet is defined as IEEE 802.3u standard, a high-speed version of
Ethernet with 100Mbps transmission rate.
Wireless LAN
Wireless Local Area Network systems (WLANs) transmit and receive data
through the air by using radio frequency (RF). This offers some advantages
like mobility, ease of installation, and scalability over traditional wired systems.
y Mobility: WLANs combine data connectivity with user mobility. This
provides users with access to network anywhere in their organization.
For example, users can roam from a conference room to their office
without being disconnected from the LAN. This is impossible with
wired networks.
y Ease of Installation: Eliminating the need to deploy network cable in
walls and ceilings, Installing WLANs is easy for novice and expert
users alike.
y Scalability: WLAN topologies are easy to change in various ways from
peer-to-peer networks for a small group of users to full infrastructure
networks for hundreds of users roaming over a broad area.
Wireless LAN is suitable for difficult-to-wire and frequently changing
environments. It’s also an ideal solution for mobile workers to access network
resource and for setting a temporary LAN when necessary
Wireless LANs can be set as “Ad-hoc” network and “Infrastructure” network.
